🔪 Step-by-Step Prep Guide
1. Choose Your Ingredients
Russet Potatoes: These are your best choice when you want a crispy outside and a fluffy center. The high starch content makes them ideal for air frying. You can also use Yukon Gold or baby potatoes if desired, but they’ll offer a creamier bite.
Sweet or Yellow Onions: Sweet onions caramelize beautifully, adding a touch of natural sugar to balance the savory flavors. Yellow onions work just as well and offer a deeper umami profile.
Olive Oil: Use extra virgin olive oil for heart-healthy fats and great flavor. You can also substitute with avocado oil or vegetable oil based on availability.
Seasoning Essentials:
- Sea salt & black pepper
- Garlic powder
- Fresh rosemary (chopped)
- Optional: smoked paprika, onion powder, dried thyme, or Italian seasoning
2. How to Cut Potatoes and Onions for Even Cooking
For best results, chop the russet potatoes into 1-inch cubes. This size ensures even cooking and allows the edges to crisp nicely in the air fryer. Slice the onions into ¼-inch strips or wedges—thick enough to hold their shape but thin enough to soften and caramelize.
Soaking the potatoes in cold water for 15-30 minutes before air frying is a game-changer if you’re aiming for ultra-crispy edges. This simple step draws out excess starch. Just make sure to pat them dry before seasoning.
3. Season and Toss
Place the cubed potatoes and sliced onions into a medium mixing bowl. Drizzle with about 1-2 teaspoons of olive oil, then sprinkle in your seasonings. Toss everything until well coated, making sure the oil and seasoning reach all surfaces.
💡 Pro tip: If you’re using fresh rosemary, add it during the last 5 minutes of air frying to avoid burning it.
4. Preheat and Cook in the Air Fryer
Set your air fryer to 375°F (190°C) and preheat it for 3–5 minutes. This ensures the potatoes and onions hit a hot surface right away, leading to a crispy texture from the start.
Place the seasoned veggies in a single layer in the air fryer basket or tray. Avoid overcrowding so that hot air circulates evenly.
Cook for 12 to 15 minutes, tossing or shaking the basket every 5 minutes for uniform crispiness. Add rosemary for the last 5 minutes, and keep an eye on the color—you’re looking for golden-brown potatoes and slightly browned, softened onions.

🧑🍳 Common Questions About Air Frying Potatoes and Onions
What kind of potatoes are best for air frying?
Russet potatoes are the go-to for crispy results. Their starchy texture leads to golden edges and a soft inside. Yukon Golds offer a more buttery, tender bite, while baby potatoes are perfect if you want a bite-sized, skin-on option.
Do I need to peel the potatoes?
Peeling is optional. Leaving the skin on adds extra fiber and nutrients. Just scrub them clean if you choose to keep the skins.
Can I use frozen potatoes or onions?
Yes, frozen potatoes can be used—no need to thaw, just increase the cooking time by 3–5 minutes. For frozen onions, ensure they aren’t overly wet, or they’ll steam instead of caramelize.
How much oil should I use?
Less is more in air frying. A light spray or 1–2 teaspoons of oil is plenty. Too much oil can make your potatoes soggy.
Can I make this recipe ahead of time?
Yes! These air fryer potatoes and onions reheat beautifully. Store leftovers in an airtight container in the fridge for up to 4 days, then reheat in the air fryer at 350°F for 5–6 minutes.
